Basic operation of novel ferroelectric CMOS circuits

A nonvolatile ferroelectric complementary metal-oxide-semiconductor (CMOS) circuit with both logic and memory functions is proposed as a new application of ferroelectric field effect transistors. The logic and memory operations of a NOT-logic ferroelectric CMOS device is demonstrated. Nondestructive readings of high and low output voltage levels of the device were performed. Data retention was measured up to 10⁵ s (1.2 days).
